MIL BAH Question (navy)

So admin is closed for like the next million years for holidays so probably be quicker to ask here...

BAH, this will be my first time collecting it basically. From what I've been told I get a lease, take it into admin, then they start he paperwork for BAH. This is fine and dandy if I find a new apartment for myself.

What if I find an apartment where I will be a roommate with a civilian who has the lease? I guess my questions are...

1) Would an "unofficial" lease signed by both of us work? Stating I'm paying them xxx/month, kind of like a contract..

2) I tried looking on the net because I had always thought there was a partial BAH of like half-BAH if you are in quarters with someone else in the military who is drawing full BAH. But if they arnt in the military do you still get only half the BAH or the full?

no, you need to get copies of the official lease from the landlord signed by everyone...and if you want (you should) you should sit down and discuss the terms of the lease since you might not be there as long as him...
